LIFTING- DEVICE.

Application filed May 15, 1922. Serial No. 560,997.

To all whom t may concern:

Be it known that I, JOHN A. Avnm, a citi zen of the United States, residing at Lava Hot Springs, in the county ot Bannocl: and State ot Idaho, have invented certain new and useful Improvements in Lifting Devices, of which the following is a specitication.

This invention relates to lifting devices, and more particularly to means for lifting motor vehicles. Y

An object of the present invention is the provision of means t'or turning a vehicle on its side to obtain ready access to the under side ot the vehicle.

It is usually necessary to get under the body of a motor vehicle to make repairs, which necessitates a repairman lying` on his back and working on a car or vehicle above him. In the present invention, I provide an apparatus by means of which a vehicle may be readily turned on its side which permits the repairman to work upon the under side oit the car and readily obtain access to any part of it.

The device consists ofV a supporting member to which the vehicle is secured and means for swinging the supporting member to a substantially vertical position.

In the accompanying drawings, I have shown one embodiment of the invention` In this showing:

Figure l is a side elevation,

Figure 2 is a rear elevation,

Figure 3 is a detail view of a clamping member,

Figure t is a front elevation,

Figure 5 is a detail view of another clamping member, and,

Figure 6 is a plan view.

Referring to the drawings, the reference numeral 1 designates a pair of horizontally disposed base members adapted to be mounted on a suitable foundation, such as the Hoor of a garage or other Flooring.' These members are connected at the rear by a transverse beam 2, and are connected intermediate their ends by a flooring 3. A pair of vertical posts l extend upwardly from the flooring and are connected at the top by a transverse beam 5. These posts may be provided with suitableI braces 6, extending outwardly at an angle (see Figure 6) and secured to the base members l. A transverse supporting member 7 is arranged adjacent the junctionv of the longitudinal members and the braces.

The upper end of each of the vertical beams is formed of -a pair of spaced meinbers 8 which may be in the form of steel plates, provided with flanges 9 which are secured to the cross member 5. This provides a space for the reception of pulleys 10, mounted on pins or shafts l1.

A pair ot hinged members 12 are secured to the front of the flooring 3 by means of hinges 13. rFliese members are connected by cross members 14e spaced from each other a distance equal to the distance between the wheels oi a motor vehicle. rFliese cross members are channel shaped, forming grooves l5 ior the reception or the wheels of a motor vehicle. As shown, (see Figure 6), a mo tor vehicle` lti is adapted to be driven on to the cross members lllwith the wheels 17 arranged in the grooves l5. The vehicle is retained in position by means of suitable clamping elements. rIhe side o'l the vehicle adjacent the vertical beams is secured in position by means of substantially L-shaped clamps 18, having a horizontal portion 19, adapted to entend beneath the cross member and an up-turned end 2O adapted to be arranged on the opposite side ot the cross member vtrom the body portion. rEhe upper end of the clamping element is provided with a hook 21 adapted to be arranged over the axle 22 of the vehicle. The clamping element is 'formed in two sections, having oppositely threaded ends which are connected to each other by a turn-buckle 22 to permit tightening. The other side of the vehicle is secured by means of a clamp shown in Figure 5 ot the drawings. This clamp comprises a pair of complementary sections 23, adapted to be secured around the axle. A rod 2A is carried by one of the clamping sections and this rod isprovided with an angular portion 25. A second rod 26 is swiveled on each of the hinged members 12 and these two rods are provided with oppositely threaded ends adapted to be con nected by a turn buckle 27.

The outer ends of the hinged members 12 are provided with side plates 28, extending beyond the hinged members and connected to each other by blocks 29. Pulleys 30 are arranged between these plates, the pulleys being mounted on shafts 31.

A rope 32 is secured in an eye-bolt 33, carried at the upper end of each of the vertical members 4. These ropes extend over pulleys 30 and thence over pulleys 10,

the pulleys being provided' with suitable grooves Ytor the reception ot the ropes. ylhe ropes are 'then carried downwardly adjacent the vertical members and pass over pulleys 34, mounted in suitable supports on the tlooring 3. Thence, they pass over guide pulleys "Eh-'- ends et the ropes are secured to a drum 36, rotatably mounted in the vertical members 4. @ne end oit the drum is provided u'ith a sha'tt extending through the vertical member and carrying a gear 37. A pinion 38 is *nonntcd on a stub shat't on the outside oit the supporting member and meshes with the gear 3T. rhis pinion is provided ivith an operating cranl 39 and a suitable locking men'iber Lit), may be arranged adjacent Unh. f coil spring il may be arranged o,A the loo. adapted to contact- With Ithe rear cross member lil when the parts are in raised position.

The operation ci the device ivill be apparent from the 'toregtgoing descrigition. The vehicle is .tirst run on to the cross members with the wheels l? received in 'the grooves l5. lt is then clamped in position to prevent displacement and raised to the dotted line position shown in Figure l of the drawings by Winding the ropes 32 on the drum 36. By means of the gearing shown, the vehicle can be raised uf'ith'ease by one man. When the vehicle is in raised position, the locking member Ll() is arranged over the crank to prevent accidental lowering. The

i spring ll engaging a portion of the movable support, tends to take up any lost motion and retain the parts rigid.

it is to be understood that the 'torni ot ny invention herewith shown and described is to be taken as a preferred example ot the same, and that various changes in tbe shape, size, and arrangement ot parts may be resorted to Without departing` from the spirit ot the invention or the scope ot the subjoined claims.

Having thus described my invention, l claim:

r. jr lifting device for motor vehicles comprising a base, a pair of spaced vertical .n'ren'ibers secured to said base, a pair ot supporting members hinged to said. base adjacent said vertical members, means 'for sup* porting a vehicle on said supporting members, and means connected between the tree ends ol' said supporting members and the upper ends ot said vertical members tor raising the tree ends of said supporting members, said raising means being arranged to permit a vehicle to enter therebeneath parallel to said vertical members.

2. fr litting device tor motor vehicles comprising a base, a pair ot spaced vertical memiers secured to said base, a pair ot supporting men'ibers hinged to said base adjL cent said vertical members, a pair oi" cross beams secured to said supporting men'ibcrs, said cross beams being spaced from each other a distance equal to the ilieel gage ot a motor vehicle and being novided with grooves 'tor the reception or the vehicle vvheels, means for clamping the vehicle to said beams, and means connected between the tree ends ot said supporting members and the upper ends of said vertical members tor raising the Egeo ends et said supporting members, said raising means being arranged to permit a vehicle to enter therebeneatn parallel to said vertical members.
